Uses for the two ports on a Deco X90
Uses for the two ports on a Deco X90

Model: Deco X90  
Hardware Version: V1
Firmware Version: 1.1.2 Build 20210722 Rel. 65801

I have a pair of Deco X90 units, running in "router" operational mode.
On each unit, there are two LAN-ports: 1 Gbps and 2.5 Gbps.

 

The primary unit is placed where the fiber optics media converter is located, and its 2.5 Gbps LAN port is connected to the WAN.

 

The secondary unit is placed in my office and is connected (using the 2.5 Gbps port) to a switching hub, creating a wired network in that room.

 

Questions regarding the primary Deco node:

- Is it in any way configurable which LAN port should be connected to the WAN (the dangerous "outside")?

- Does the unit somehow detect which port is connected to a WAN, and not a LAN?

- What would happen if I moved the WAN cable from the 2.5 Gbps port to the 1 Gbps one?

- Can the other port be used for something?

 

 

Questions regarding the secondary Deco node:

- Can both port be used to connect wired units to the LAN?

@MorganC 

Hi, the following information might help with your inquiries.

Deco supports WAN/LAN auto-sensing.

Normally, for the main Deco, the port to the fiber modem is the WAN port since the fiber modem will assign an IP address to Deco through this port, then the port left will be LAN port that could be connected to the network switch.

So the 2.5ghz port of the main Deco could be used as either a WAN or LAN port.

For the satellite unit, when it is on wireless backhaul, both Ethernet ports will be LAN ports and you could connect computers or other Ethernet devices to these ports.

@TP-Link , thanks for your reply.

 

So, if I move the wan cable from one ethernet port on the main Deco X90 to the other port on the same Deco, it will autosense this?

 

From what you said, I assume that this this a valid setup?


 

 

Will the Decos also autosense a wired backhaul connection?

MC

Yes

The following is a valid setup.

Normally, the "Wireless/Ethernet backhaul" refers to the connection between main and satellite Deco nodes.

Once the WAN port is confirmed, the left will be LAN port. In other words, if neither port on the main Deco has been detected as the WAN port, both ports will be recognized as available WAN ports.

@TP-Link , thanks.

 

To clarify my wired backhaul question:

Assume I use the wifi backhaul setup in the image above.

 

Then, I find a way to install a cable through my house, between the two decos.

I connect this cable like so:

 

 

Will the Decos then detect that there now is a wired backuhaul available and start using it?

 

Regards 

Morgan
